6.29.1. 安装 Coreutils
|
||
</h2>
|
||
<p>
|
||
POSIX 要求 Coreutils 中的程序即使在多字节地区也能正确识别字符边界。
|
||
下面的补丁修复这个不兼容性以及其它一些和国际化相关的 bug。之后确保
|
||
<code class=
|
||
"filename">Makefile.in</code> 文件的时间戳比其它所有文件都晚以免出现
|
||
<span class="command"><strong>make</strong></span> 错误：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">patch -Np1 -i ../coreutils-8.23-i18n-1.patch
|
||
touch Makefile.in</kbd>
|
||
</pre>
|
||
<div class="admon note">
|
||
<img alt="[Note]" src="../images/note.png" />
|
||
<h3>
|
||
注意
|
||
</h3>
|
||
<p>
|
||
之前在这个补丁中发现了很多 bug。当向 Coreutils 维护者报告新 bug
|
||
的时候，请先检查没有该补丁是否可以重现 bug。
|
||
</p>
|
||
</div>
|
||
<p>
|
||
现在准备编译 Coreutils：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">FORCE_UNSAFE_CONFIGURE=1 ./configure \
|
||
--prefix=/usr \
|
||
--enable-no-install-program=kill,uptime</kbd>
|
||
</pre>
|
||
<div class="variablelist">
|
||
<p class="title">
|
||
<strong>配置选项的含义：</strong>
|
||
</p>
|
||
<dl class="variablelist">
|
||
<dt>
|
||
<span class="term"><code class=
|
||
"envar">FORCE_UNSAFE_CONFIGURE=1</code></span>
|
||
</dt>
|
||
<dd>
|
||
<p>
|
||
该环境变量允许以 root 用户权限编译软件包。
|
||
</p>
|
||
</dd>
|
||
<dt>
|
||
<span class="term"><em class=
|
||
"parameter"><code>--enable-no-install-program=kill,uptime</code></em></span>
|
||
</dt>
|
||
<dd>
|
||
<p>
|
||
该选项的目的是防止 Coreutils 安装其它软件包后面会安装的
|
||
二进制包。
|
||
</p>
|
||
</dd>
|
||
</dl>
|
||
</div>
|
||
<p>
|
||
编译软件包：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make</kbd>
|
||
</pre>
|
||
<p>
|
||
如果不运行测试套件的话跳到 <span class="quote">“<span class="quote">安装软件包</span>”</span>
|
||
</p>
|
||
<p>
|
||
现在可以运行测试套件了。首先，运行需要以 <code class="systemitem">root</code>
|
||
用户运行的测试：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make NON_ROOT_USERNAME=nobody check-root</kbd>
|
||
</pre>
|
||
<p>
|
||
我们会以 <code class=
|
||
"systemitem">nobody</code> 用户运行剩下的测试。但是，一些测试要求用户
|
||
属于多个组。由于不跳过这些测试，我们会添加一个临时的组并添加用户
|
||
<code class="systemitem">nobody</code> 作为它的成员：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">echo "dummy:x:1000:nobody" >> /etc/group</kbd>
|
||
</pre>
|
||
<p>
|
||
修复一些权限问题以便非 root 用户可以编译和运行测试：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">chown -Rv nobody . </kbd>
|
||
</pre>
|
||
<p>
|
||
现在运行测试。确保 <strong class=
|
||
"userinput"><code>su</code></strong> 环境中的 PATH
|
||
包含了/tools/bin。
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">su nobody -s /bin/bash \
|
||
-c "PATH=$PATH make RUN_EXPENSIVE_TESTS=yes check"</kbd>
|
||
</pre>
|
||
<p>
|
||
在虚拟主机中 stty-pairs 测试很可能失败，而在 X 终端中则能通过。
|
||
</p>
|
||
<p>
|
||
移除临时组：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">sed -i '/dummy/d' /etc/group</kbd>
|
||
</pre>
|
||
<p>
|
||
安装软件包：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">make install</kbd>
|
||
</pre>
|
||
<p>
|
||
移动程序到 FHS 指定的位置：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class=
|
||
"command">mv -v /usr/bin/{cat,chgrp,chmod,chown,cp,date,dd,df,echo} /bin
|
||
mv -v /usr/bin/{false,ln,ls,mkdir,mknod,mv,pwd,rm} /bin
|
||
mv -v /usr/bin/{rmdir,stty,sync,true,uname} /bin
|
||
mv -v /usr/bin/chroot /usr/sbin
|
||
mv -v /usr/share/man/man1/chroot.1 /usr/share/man/man8/chroot.8
|
||
sed -i s/\"1\"/\"8\"/1 /usr/share/man/man8/chroot.8</kbd>
|
||
</pre>
|
||
<p>
|
||
BLFS 以及上游中的一些软件包希望下面的程序在 <code class="filename">/bin</code>
|
||
中，确保把它们放到了那里：
|
||
</p>
|
||
<pre class="userinput">
|
||
<kbd class="command">mv -v /usr/bin/{head,sleep,nice,test,[} /bin</kbd>
